Add NamedArrayPartition and Float32 ArrayPartition to precompilation workload

This improves time-to-first-execution (TTFX) by adding commonly-used operations
to the precompilation workload:

1. NamedArrayPartition - constructor, property access, indexing, broadcasting, similar
2. Float32 ArrayPartition - constructor, indexing, broadcasting, similar, recursive_mean, recursivecopy

Performance improvements:
- Float32 ArrayPartition broadcasting: ~0.4s → 0.00008s (~5000x faster)
- Float32 ArrayPartition constructor: ~0.05s → 0.0003s (~180x faster)
- NamedArrayPartition operations now sub-millisecond

Package startup time remains unchanged at ~0.26s. Only 4 low-impact invalidations
were found (all necessary for package functionality).
